The use of aged wood fines is more common in organic soil mixes than conventional synthetic soil mixes. It mimics the natural and organic activity that occurs on the forest floor. For nearly 100 years, we have used fully composted aged wood fines in our soil mixes for three reasons – Better soil structure with its slightly larger particle size helps air and water penetrate deeper into the soil, allowing for better root development and overall plant health – Excellent food source for beneficial soil microbes which help plants resist pests and disease – A more sustainable resource benefiting the environment. No doubt, it does look different than conventional synthetic peat-based soil mixes.
